Dave D., have you, or anyone else, tried to operate one or both of the
MAX232x RS232 drivers from its own switching frequency followed by a
doubler or triper to get even higher (or lower) voltage ? I have a project
where I could use 70Vdc at very low power. I think that this will work.
What do you think ? What does the MAX232 spec say about overloading the
outputs ?  Afair RS232 allows dead shorts on the outputs indefinitely.
True for MAX232 ?
